With the Discovery's spore drive taking them into the mirror universe and Lieutenant Stamets completely incapacitated, the crew discovers the horrors of the Terran Empire and must masquerade as their counterparts to find a way home. Lieutenant Tyler discovers there may be more to his post-traumatic stress disorder than just remembering torture at the hands of the Klingons.

Continuity Edit

  • L'Rell attempts to use a Klingon prayer to reawaken Ash Tyler's memories of Voq. This prayer was previously used in "Battle at the Binary Stars" where it was recited by Voq and T'Kuvma shortly before the latter's death.
  • It is established that the ship might have entered a different universe through detecting a quantum signature, the dialog closely mirroring a similar scene in "Parallels". This is also the first explicit hint that the mirror universe is of the same nature as the infinite quantum realities of that episode.
  • The Vulcans or a faction of them are shown to be once more in rebellion against the Terran Empire, a century after the mirror Hoshi Sato used the USS Defiant to become Empress of the Terran Empire in January 2155. In "Mirror, Mirror", Mirror Spock is depicted as serving as XO and science officer of the ISS Enterprise in 2267, under the mirror universe version of Captain Kirk.
  • The ISS Shenzhou and ISS Discovery are shown not to have their doors marked with the emblem of the Terran Empire anywhere aboard, unlike either ISS Enterprise or the ISS Avenger. Although the emblem doesn't appear on the doors of the ships, it is shown emblazoned on the floor of the ISS Discovery bridge.
  • The emblem of the Terran Empire is shown in a different design than previously shown in both "Mirror, Mirror" and the "In A Mirror, Darkly" two-parter. Curiously, the Earth itself is mirrored in the emblem, which was not previously the case.
  • Chronologically, this is the earliest reference to the Klingons of the mirror universe.
  • Tilly being captain in an alternate universe was foreshadowed in "Si Vis Pacem, Para Bellum", when an increasingly confused Stamets addresses her by that rank.
  • Lorca adopting a Scottish accent as the ISS Discovery's engineer references Montgomery Scott. Some have taken this to mean Lorca probably either knew or knew of Scott by the time this episode is set. [2] (At this point in time, Scott had been in Starfleet for about fifteen years.)
  • Burnham impersonating her mirror counterpart (who is presumed dead) is reminiscent of Benjamin Sisko having to impersonate his presumed dead counterpart in DS9: "Through the Looking Glass".
  • This is the first time that a ship is seen impersonating its mirror universe counterpart with the USS Discovery having its hull remarked to read ISS Discovery and other Imperial Starfleet hull markings to appear as its double.

Reception Edit

  • At the Continuing Voyage Tour convention in Chicago on 16 September 2017, Jonathan Frakes revealed that Star Trek: Discovery would be doing a mirror universe episode. [3] [4]
  • CBS All Access is promoting this episode as the start of "Chapter Two", due to premiere eight weeks after the previous episode, which was promoted as the end of "Chapter One". While previous series often had periods which did not see a new first-run episode being broadcast (usually rerunning earlier episodes in the interim), particularly when in syndication, this is the first explicit broadcast break in a Star Trek series, making this the first mid-season premiere in Star Trek history.
